Implementing the Cover Under Protective Screen (CUPS) System

The Citrus Under Protective Screen (CUPS) growing strategy for fresh fruit has produced results that confirm strong fruit production with high quality in systems of screen house-grown citrus. Recent research projects found that the screen house-grown citrus (in houses of approximately 20 acres) remained free of Asian citrus psyllid (ACP) for every weekly inspection in 2017-2018. There were no detectable cases of HLB disease in the screen house both by visual or PCR testing after nearly four years. This is a viable alternative for fresh fruit growers.
